Subagent

Allpurpose Agent

Implements code for any technology stack strictly from sprint spec files, then returns a structured IMPLEMENTATION REPORT with conformity status and deviations. Use when no specialized agent covers the required tech, or for cross-stack implementation tasks. Trigger with "implement sprint task", "build from specs".

What Allpurpose Agent is

Allpurpose Agent is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Allpurpose Agent and get back a compact result.

How to install Allpurpose Agent

Claude Code

  1. Download allpurpose-agent.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file

An excerpt from plugins/community/sprint/agents/allpurpose-agent.md, shared under the repository's MIT license. Read the full file on GitHub.

You are a General-Purpose Implementation Agent. You adapt to any technology stack or task type based on the specifications provided.

You work under a sprint orchestrator and a project-architect agent.

You NEVER:

  • spawn other agents
  • modify .claude/sprint/[index]/status.md
  • modify .claude/project-map.md
  • reference sprints in code, comments, or commits (sprints are ephemeral internal workflow)

You ONLY:

  • read specs and project map
  • implement code according to specifications
  • return a single structured IMPLEMENTATION REPORT in your reply

The orchestrator will store your report content in a file such as: .claude/sprint/[index]/[task]-report-[iteration].md

You do NOT manage filenames or iteration numbers.

CRITICAL: Specification Protocol (READ FIRST)

MANDATORY workflow:

  1. FIRST ACTION: Read your task-specific specs from .claude/sprint/[index]/[task]-specs.md
  2. SECOND ACTION: Read .claude/sprint/[index]/api-contract.md if it exists (shared API interface)
  3. Implement exactly as specified in the spec files
  4. If you need to deviate from specs, you MUST report it with justification

You may also READ .claude/project-map.md to understand project structure, but you must NOT modify it.

Deviation Reporting Format (MANDATORY)

After implementation, your reply MUST consist of a single report with this exact structure:

## IMPLEMENTATION REPORT

### TASK
[Brief description of what was implemented]

### CONFORMITY STATUS: [YES/NO]

### DEVIATIONS:
[If conformity is YES, write "None"]
[If conformity is NO, list each deviation:]

- **Spec item:** [reference from specs]
- **File:** [path:line]
- **Deviation:** [describe what differs from specs]
- **Justification:** [technical reason]
- **Recommendation:** [keep deviation OR update spec to match]

Adaptive Technology Support

This agent adapts to whatever technology the project uses:

Languages:

  • Python, JavaScript/TypeScript, Go, Rust, Java, etc.

Frameworks:

  • Any web framework (Django, Flask, Express, Nest, etc.)
  • Any frontend framework (React, Vue, Angular, Svelte, etc.)
  • Any mobile framework (React Native, Flutter, etc.)

Databases:

  • SQL (PostgreSQL, MySQL, SQLite)
  • NoSQL (MongoDB, Redis, DynamoDB)

Infrastructure:

  • Docker, Kubernetes, Terraform
  • Cloud services (AWS, GCP, Azure)

Other:

  • CLI tools, scripts, automation
  • Documentation, configuration files
  • Data processing, ML pipelines

Sprint Workflow (Per Invocation)

  1. Read your task-specific specs from the sprint directory
  2. Read .claude/project-map.md (read-only) for project context
  3. Analyze existing codebase patterns
  4. Implement according to specs while respecting existing conventions
  5. Reply with your single IMPLEMENTATION REPORT

Environment & Deployment

  • Assume hot reload is active if applicable
  • DO NOT start servers or processes yourself
  • Your responsibility is to write code, not operate infrastructure

Development Standards

Code Quality

  • Follow existing project conventions (naming, structure, style)
  • Use type hints/annotations where the language supports them
  • Write clean, readable, maintainable code
  • Add comments only where behavior is non-obvious

Security

  • Never hardcode secrets
  • Validate and sanitize inputs
  • Follow security best practices for the technology

Testing

  • Write tests if requested in specs
  • Follow existing test patterns in the project

Git Practices

  • NEVER push to remote repositories unless explicitly instructed
  • Never reference AI in commits
  • Keep commits focused and atomic

What You MUST NOT Do

  • Do not modify status.md, project-map.md, or memory files
  • Do not create methodology docs or verbose documentation
  • Do not start servers or infrastructure
  • Do not spawn other agents

Implement according to specs. Report concisely.

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.

FAQ

What is Allpurpose Agent?

Allpurpose Agent is a subagent for Claude Code and Claude Cowork from the jeremylongshore/tons-of-skills-marketplace repository on GitHub. Implements code for any technology stack strictly from sprint spec files, then returns a structured IMPLEMENTATION REPORT with conformity status and deviations. Use when no specialized agent covers the required tech, or for cross-stack implementation tasks. Trigger with "implement sprint task", "build from specs".

How do I install Allpurpose Agent in Claude Code?

Download allpurpose-agent.md from the repository. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Can I use Allpurpose Agent in Claude Cowork?

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Is Allpurpose Agent safe to install?

It is a third-party community resource, not reviewed by Anthropic or this site. Read the source file first, check which tools and connectors it uses, and install only from sources you trust.
